One of my 80mm latex flat spring diaphragms
The photo: The soft stretchy natural latex dome has a small triangle enclosing the size of the device in mm in raised characters in the center of the domes outer surface. The white curved and notched wand above the diaphragm is an introducer used to aid in insertion. Because the rim folds in a single plane the flat spring is ideal for use with a deep thrusting partner and is the style preferred by professional rubber-escorts because it is almost impossible to under-thrust the rim. This style diaphragm can be worn with the dome reversed so the raised lettering is on the inside if the sensation is too intense for a lover.
The Fall semester at UNLV: The Fall semester begins at UNLV on Monday August 27 and ends on Saturday December 15. Some Grad students are already returning, reestablishing housekeeping and getting their Gyn visits over with prior to resuming fetish based sexual activity while at school. The rubber-girls are more likely to come in for pelvic exams since they all want to make sure the vaginal rubber devices they wear are still in good condition and properly sized after several months of heavy use during vacation.
The candidate: Judy, a 26 y/o Ph.D. candidate in psychology, and a sorority member with an active fetish life as a rubber-chick came in for her usual 6 month pelvic and full STI panel. I worked her up and did her pap and diaphragm fit check. I had already heard of her as a doctorial candidate, but she also caught my attention in the Spring - when she was assigned to me as a new patient since her regular practitioner left the clinic - because there are so few female rubberists not to mention gorgeous and smart ones. Her vaginal muscle tone is very strong, and her pelvic dimensions (deep post-pubic vault and vaginal length) are almost identical to mine, so she wears the same size diaphragm I do, an 80mm though she is four inches taller than me. Another amazing similarity is that for vaginal toning she uses a set of .75 inch solid stainless steel balls weighing 1.0 oz. each just like I do! I thought I was the only one using solid steel balls, but obviously not, but I do plan to introduce them into the AST class I’ll be teaching to upper form students at St Lucy’s this Fall. I have seen other female patients who were a close match to me physically, but they were pure Vanilla. Judy already into the lifestyle and wanting to go further will be perfect for my purposes.
I knew Judy was an active rubberist because she and I have discussed latex catsuits and vaginal plugs and she had been wearing a silicone All-Flex for protection during rough sex, but this time I suggested she change to a flat spring latex diaphragm as latex has far better heat transfer properties and it is nearly impossible to under-thrust a flat spring rim thus making it both more comfortable and safer to wear. She has also used our search service [putting medical records on-line has made this easy] to remotely check potential sexual partners medical records for STIs, latex allergies and other possible medical problems prior to entering any sort of physical relationship, so I knew she was a player. All of which makes her an ideal candidate for an experiment I want to try to see if I can replicate in other female rubberists and their partners the pleasure I get from wearing a Reflexions latex flat spring diaphragm.
Judy’s faculty advisor had contacted me on her behalf last Spring asking if I would help guide her doctorial candidate into the lifestyle in the valley. So I was already aware she would be contacting me when she was ready and this past week she broached the subject during her semi-annual exam. The topic of her doctorial thesis will be: ‘Women as enablers in male deviant sexual behavior’. She is a Switch and can be submissive or dominant as necessary to meet her personal or research needs. She asked for my help in meeting suitable male rubberists to study their various techniques and learn what they get out of heterosexual intercourse in a D or S relationship. She plans to develop active sexual relationships with at least eighteen men over the next two years and if that sample isn’t broad enough she said she may begin hunting suitable partners in the general male population. I decided the safest thing to do would be to introduce her to the male escort trainees who are rubberists and who have been screened for STIs and mental stability so she doesn’t get her air hose cut while at the bottom of a training pool during a dive-sex encounter. There seems to be an inexhaustible supply of high quality male rubberist trainees so as long as she stays with our trainees I don’t think she will run out of suitable men and these guys have far more stamina that a pick-up from a meat market so she will have to pace herself to prevent becoming physically exhausted from research.
Most of our trainees enjoy sex with women who wear rubber (catsuits, dive gear and vaginal barriers), pointe-shoes and like rough sex which are the fetish aspects Judy is most comfortable with so far. She is a qualified open water SCUBA diver, which is good enough for dive-sex. She also attended several summer sessions at SAB and takes private ballet lessons so she may be strong enough that I can let her safely try ballet-sex in pointe shoes. We’ll see about that. Her contemplative training needs to be far enough advanced that she can compartmentalize control of her feet and legs from her sexual needs so her legs don’t collapse during orgasm while en pointe. She enjoys the discomfort of pointe shoes and deep thrusting by large men so she seems Ideal for the research I want to conduct. Since we both need different men penetrating her this will give her an ideal opportunity to meet some of the men she will be conducting intimate research with over the next few months. I never thought I’d be an advisor to a Ph.D. candidate, but of course I’m a technical resource rather than an academic advisor.
The anterior fornix and latex diaphragms: On average, the ectocervix (the part of the cervix that protrudes into the vagina) is 3 cm long and 2.5 cm wide. The 3 cm length of the anterior cervical wall and the anterior vaginal wall form a gap called the anterior fornix which along with the cervix is covered by the dome of a contraceptive diaphragm. Thus the anterior fornix is typically a 3 cm cleft into which the stretchy latex membrane of a flat spring diaphragm can be pushed by the force of a thrusting penis, assuming the shaft is long enough to reach and penetrate the anterior fornix of an aroused partner.
The latex Reflexions flat spring diaphragm is the only maker and style that allows a male to fully penetrate his partner’s anterior fornix while she is wearing it. That’s because the silicone domes of other major diaphragm makers (Ortho and Milex) aren’t elastic enough to be stretched and pushed into the depths of the cleft. The latex dome has heat transfer characteristics far superior to a silicone diaphragm so thrusting into the latex membrane of the Reflexions is almost like skin-on-skin contact. The flat spring rim of the Reflexions, which flexes in a single plane, aids in successful fornix penetration by providing a stable rim to allow stretching the dome over the cervix and deep into the cleft.
I know for a woman it sounds as though its business as usual having a partner thrust into her anterior fornix while being taken in missionary, but when using a latex Reflexions diaphragm that’s not necessarily the case. I’ve known for several years that there can be unanticipated benefits for me and my partner when I’m taken that way with him targeting my anterior fornix as the primary goal of his thrusts. When everything is just right the benefits are:
- For me: The dome stretched over the tip of my cervix as his penis thrusts into my anterior fornix puts pressure on my uterus forcing it a bit deeper slightly extending the depth of my vagina providing some thrust buffering from a long penis while moving the rim across my G-spot giving me the possibility of having both a G-spot and cervical orgasm simultaneously.
- For him: The raised logo and size (in the center on the exterior of the dome) provide a stimulation point for my partner’s frenulum while at the same time the tautly stretched latex membrane forced into the fornix by his thrust squeezes the head of his penis multiplying the sensation of an tightened vaginal grip. My experience has been that if my partner is cut he will enjoy the increased sensation and if his size is just right I can adjust my hips and make him come regardless of how still and deep he tries to stay to avoid reaching orgasm. However, if my partner is uncut his tip is often more sensitive to the textured latex which leads to premature ejaculation or occasionally rubbing him raw. If a partner is that sensitive I can wear the diaphragm inverted, with the logo on the inside, so he feels only the smooth latex gripping his glans as he plunges into my anterior fornix.
